It's still not clear what the first Star Wars standalone film will be about, but The Hollywood Reporter has word as to who might be in it: Orphan Black star Tatiana Maslany and The Girl With the Dragon Tattoo's Rooney Mara are both testing for the female lead in the film, according to the trade publication.

Felicity Jones -- who played Felicia Hardy in Amazing Spider-Man 2 and is up for the Best Actress Oscar for her role in The Theory of Everything -- is also named as a potential contender for the role, though her schedule shooting Da Vinci Code sequel Inferno may complicate matters. Disney and the representatives for the respective actors declined comment on THR's story.

Much remains unrevealed about the initial Star Wars spinoff -- the first of multiple planned films outside of the latest trilogy -- other than Godzilla's Gareth Edwards is slated to direct, and the film has a scheduled release date of Dec. 16, 2016. Rumors and speculation have ranged from the film focusing on a young Han Solo, Princess Leia or Boba Fett, but nothing has been established for certain -- and the film is currently looking for a writer, as Gary Whitta recently left the production. Fantastic Four reboot director Josh Trank is on board to helm a subsequent Star Wars standalone film.
